In a chemical reaction, a reactant binds to an enzyme at a region known as the

• catalyst
• product
• substrate
• active site

Which of the following are examples of lipids?

• DNA & RNA
• sugars & starches
• fats, oils, waxes
• enzymes & antibodies 

What does  the lock-and-key model state?

• any substrate can bind an enzyme 
• only specific amino acids can build carbohydrates 
• specific substrates bind specific enzymes 
•  nucleotides must fit like a lock and a key 

The optimum pH for the enzyme Trypsin is

• 2

• 4

• 6

• 8

When you step out into the cold, your body shivers in order to keep its temperature at 98.6F.

• All living things use energy
• All living things contain cells
• All living things maintain homeostasis
• All living things grow
